The clinical observation of immediate loading in complete edentulous jaws

Objective To observe the implant retention rate and bone changes around the implant after full-mouth immediate repair and immediate loading in complete edentulous jaws. Methods A total of 57 cases of full-mouth immediate repair and immediate loading in complete edentulous jaws（48 cases with single jaw,9 cases with complete upper and lower jaws） were selected,and the definitive restorations were made after 6 months of transitional dentures. Results In 57 cases,the survival rate of implants was 99.6% before the definitive restorations,and the surrounding mucosa of the implant was healthy,and there was no obvious absorption around the implants neck.The changes of bone height were-0.3（-0.4,-0.2） in the upper jaws and-0.2（-0.3,-0.1） in the lower jaws. Conclusions Immediate full-mouth repair and immediate loading can meet the requirements of aesthetic and masticatory function during the transitional period of patients.The implant has a high retention rate,and provides a good reference for the determination of occlusal relationship after permanent restoration.
